Research on a Scale-Based Feature Image Retrieval Algorithm
Haijian Zhang, Dan Sun · 2023
With the continued evolution of information retrieval technology, the necessity for prompt and precise image information depiction has become paramount. Traditional methods primarily focus on extracting image features, encompassing texture, color, and spatial relationships. This study, however, introduces a scale-based feature image retrieval algorithm. This technique serves as a method for local feature vector extraction, capturing scale angle variations and exhibiting affine invariant characteristics. In assessments, this algorithm consistently outperforms its conventional counterparts, especially in matching scenes from varied viewpoints.
